Conference : Can we live without a calendar?
23 novembre 2019 10:45 - Amphi Louis Armand

In 1582, a calendar change had a massive impact on people’s everyday lives. Jules Caesar’s calendar, which had been observed for fifteen centuries, was now deemed unsuitable. There was a 10-day lag from the expected start of spring, and things seemed likely only to worsen. So, in 1582, Pope Gregory XII decided to remove 10 days from the month of October! And what about today? In our era of satellite-controlled GPS, our watches neglect the fact that the Earth does not spin in a perfect circle, and our calendar seems to be set in stone. Without a glitch, our calendar determines the scheduling of our activities, codifies our past, and presages our future. Nevertheless, the rollover to the year 2000 created fears that our computers would fail as we capped off the millennium. We have forgotten how to tell the time based on the sun, and we now live according to a new form of dependence. Some long for a slower pace of life and less precision. Are we in synch with our calendar? Could we live without it?
